intel 950 and direct rendering

Hi!
I am having a problem with direct rendering on my intel 950 (acer Aspire 5630).

Although it says

glxinfo | grep direct
direct rendering: Yes

direct rendering doesn't seem to work. openGL apps like google earth run very slowly, and glxgears just hangs with no wheels turning (but i see the wheels).

Glxgears has this output:

glxgears
XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0"
      after 6359 requests (4078 known processed) with 0 events remaining.

Here is my xorg.conf:

I already took some tips from this forum and the wiki (adding the user to "video" group, setting DRI to video group, etc.) but without success :-(

moin Hauke

this could be a problem in google-earth version 4.3! Did you test already to deactivate the atmosphere?

Re: intel 950 and direct rendering

I'm getting the same also. Gears not moving, among other things; RSS Screen savers are black screens, etc...

Edit: I should state that my card is an intel GMA900. Acer TravelMate

Re: intel 950 and direct rendering

It looks like this is a known problem with the mesa libraries. I have also seen this happen with glxgears, however 3D rendering still works for me (Intel 945GMA). This may be of interest to you: http://bugs.archlinux.org/task/10500

Re: intel 950 and direct rendering

If you've completely followed the wiki on AIGLX, then theoretically you should be fine.. Odd, I get this:

2716 frames in 5.0 seconds = 543.172 FPS
2697 frames in 5.0 seconds = 539.304 FPS
2655 frames in 5.0 seconds = 530.971 FPS
XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0"
      after 59622 requests (4659 known processed) with 0 events remaining.

My wheels are stuck too, but compositing runs fine... Hmm..

Re: intel 950 and direct rendering

Even if you have the drivers set up properly, the gears won't move.  You can just ignore it.

Re: intel 950 and direct rendering

I had trouble with other gl-application, while I didn't solve this problem, For example, desk gl-chess was disappeared after some moving on it. So, best solution is rebuilding mesa with abs. There are no common solution for this problem, because build with not 'generic' flag is not suitable for binary package.

Re: intel 950 and direct rendering

Hi metal!
Ok, i should rebuild the "mesa" package - but what do you mean with "not generic flag"? Should i change something in the PKGBUILD?

[edit] ok, i see - it's this:

Comment by Andrey Gusev (metal) - Friday, 30 May 2008, 19:17 GMT-4
I removed -L$(TOP)/lib64 from patch. It doesn't have influence, but I don't sure. Changed /etc/makepkg.conf
CFLAGS="-march=i686 -mtune=generic -O2 -pipe"
CXXFLAGS="-march=i686 -mtune=generic -O2 -pipe"
on
CFLAGS="-march=i686 -mtune=pentium-m -O2 -pipe"
CXXFLAGS="-march=i686 -mtune=pentium-m -O2 -pipe"
Rebuilt package, upgraded and it became working for me!

Problem is i can't find out which -mtune i need for my intel core duo T5500 - it's not pentium-m i suppose - or is it?

cat /proc/cpuinfo says this for me:

Re: intel 950 and direct rendering

thanks!
So i don't need the "-mtune" option? The wiki says this:

Pentium 4/Prescott/Celeron 'D'/Pentium 'D'/Core Solo/Core Duo

CHOST="i686-pc-linux-gnu"
CFLAGS="-march=prescott -O2 -pipe -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"

[edit] ok, the -mtune actually doesn't seem to matter. I recompiled mesa and the glxgears spin now (and a bit faster than before, 891 fps instead of 750) but google earth is still very slow (but also a bit faster than before)...
